Sand Blasting

Postby SomethingMetal » Fri Jan 27, 2012 12:45 pm

Is there anybody here that can give me some input on a good pressurized sandblasting tank? I have seen them range from $150-$1000. I mean what is the big difference between them? Holds blast media and lets it flow through my nozzle. Not sure what makes one tank better than another.

I'll tell you what little I know . . .

1st. Size - media holder size (tank)

2nd. Nozzle size must not be too big for your compressor. Check CFM requirements.

3rd. Method of flow - some are gravity / siphon fed & others are pressureized.

Also make sure it will handle all media types. silica sand, glass bead, metal shot, aluminum oxide, nut shell

Look at - http://www.tptools.com/d/12_Sandblasting-Cabinets.html. for cabinets.

Look at - http://www2.northerntool.com/abrasives- ... asters.htm for portable blasters.

Do not overlook safety . . . hood, respirator etc.

Unprotected sand blasting is far more dangerous for your health than smoking. . .

This would be my choice - http://www.northerntool.com/shop/tools/ ... 744_138744

My 2 cents . . .

I have this and I love it. I use it almost every day and well worth the $1600 I paid for it.

If you are referring to the pressure pot there is almost no difference except for the hardware and hoses. All the cheap HB, Northern tool etc are all Chinese made. The very few pots made in USA are more money. I own 3 pots and have changed the gages,hoses and mixing valves on all of them over time. I use hydraulic hose, it is thicker and less prone to blow-outs. I up grade all the gages to better USA made ones. The single best upgrade is the mixing valve on the bottom. I use a valve made by PAB - Pickard Artistic Blasting in OK. The valve is much better than the stock one and prevents many plug-ups. They also make a great variable flow trigger style gun. You have infinite control over the blast rate. They also have a wide selection of high quality nozzles. None of this is cheap but what a difference it makes. I still do some etching on stone and mirrors and this is the set up I use. If you are blasting rust only the trigger gun is not needed but the mixing valve is worth it.

That is what I thought as well then I broke down and bought a Texas Blaster. Much better quality and I never fight it, it just plain works and works good. I owned several of the others and there is no comparison. It does cost more, but worth every penny.

I built my portable sandblaster from a 100lb propane tank. I cut the bottom out, put a fill hole in the center, inverted it and welded the bottom back in. Been using it for 30+ years.

Some of the differences are whether or not the sandblast pot is ASME ceritified in its welds. If its not there is risk of a tank failing and causing harm. Additionally the valves you get with the pot may vary from a basic open closed valve to a valve that allows for complete control. The chart below Image and paste shows the air requirements for different nozzle sizes (remember sandblasting could require huge compressed air). If your looking at a basic blast cabinet typically your looking at a bit of a higher end cabinet as most are suction feed pressure feed cabinets cost more. If more information is helpful this guide on sandblast pots https://www.pittsburghsprayequip.com/2016/08/17/sandblast-pot-buying-guide/may help.
